Accumulation ability of the pepper plant (Capsicum annuum L.) for lead element in two different texture of soils

Abstract

A biological experiment has been carried out in the Department of Soil and Water Resourcesthe College of Agriculture-AL-Qasim Green University in summer season (2014) in order to identifythe effect of adding different levels of soild sewage sludge (sludge) and Pb and the interaction betweenthem in the pepper plant (Capsicum annuum L.) in two different texture soils clay soil (s1) and sandsoil (s2) , a biological experiment involved cultivation in plastic pots included three levels of lead infrom of nitrate phase (0 , 234 , 468) mg.kg-1 respectively, and four levels of sludge (0 , 30 , 60 , 90)gm.kg-1 and two soils (clay s1 and sandy s2) and the cultivation of pepper plant (Capsicum annuum L.), The design CRD was used in the stady, included three levels of pb and four levels of sludge twodifferent texture soils with five replicates bringing the number of experimental units to be (120) unit ,results showed: That significant increase when adding the sludge with level (90) gm.kg-1 in the overalltotal and available concentrations of lead in soils of case-study and the presence of a significantincrease when adding the sludge with level (90) gm.kg-1 to contaminated soil with lead in theconcentration of total and available element (234, 468) mg.kg-1 .And for the total concentration ofelement which absorbed by plant the results showed that the highest of lead accumulation in plantwas when adding levels (90) gm.kg-1 of heavy element (sludge).
